Impedance

When analyzing the impedance of the Kyocera AVX TCJD476M025R0100E Capacitor at a 1 Volt test frequency, it's important to consider the behavior of this component in comparison to the benchmark data. Overall, the impedance values of this capacitor are within a comparative range to the benchmark. However, certain deviations can be observed which demonstrate this component's specific characteristics and performance.

For instance, at a test frequency of 5 Hz, the benchmark average impedance is documented as 656.9 Ohms, whereas the Kyocera AVX TCJD476M025R0100E Capacitor exhibits a slightly smaller impedance value of 651.7 Ohms. On the other hand, at a significantly higher frequency of 250 kHz, the benchmark average impedance is reported to be 293.6 milliohms, but the tested capacitor demonstrates a far lower impedance of 48.88 milliohms - a notable improvement compared to the benchmark, indicating favorable performance at high frequencies.

Upon testing at a higher voltage of 10 Volts using LCR measurements, the TCJD476M025R0100E Capacitor continues to perform within the acceptable range provided by the statistical benchmark, even as the impedance values display variations. For example, at 5 kHz, the capacitor's impedance measures 702.7 milliohms. Although this value is higher than the result obtained with the 1 Volt testing, it remains well within the benchmark parameters, showing a stable performance change over different voltages. Moreover, at an elevated frequency of 600 kHz, the capacitor maintains an impedance value of 29.16 milliohms, which constitutes a considerable improvement in comparison to the benchmark data.

In certain frequency domains, the Kyocera AVX TCJD476M025R0100E Capacitor surpasses the benchmark values by exhibiting lower impedance values, further indicating the potential for better performance in comparison to other capacitors in the Tantalum - Polymer: Molded market segment. These observations demonstrate the component as an advantageous choice for applications that require stable performance and low impedance values across a wide range of test frequencies and voltages.

Capacitance

The KYOCERA AVX TCJD476M025R0100E Tantalum - Polymer: Molded Capacitor features an impressive nominal capacitance value of 47μF with a tolerance of ±20%, a crucial aspect for determining the capacitor's suitability for various applications. The component shows remarkable consistency and competitive performance in comparison with the statistical benchmark at a voltage of 1 Volt, across a wide range of test frequencies. The TCJD476M025R0100E Capacitor adheres closely to the average series capacitance benchmark, illustrating its solid performance characteristics.

At a 5Hz test frequency, the component's series capacitance measures 48.76μF, conveniently positioned between the benchmark's minimum (40.66μF) and maximum (69.99μF) values. Performance consistency is maintained for 10Hz to 500Hz test frequencies, with the series capacitance remaining within the established benchmark range. It is worth noting that at 50Hz the component's series capacitance measures 47.35μF, slightly above the benchmark's minimal value (39.76μF), yet it still denotes a consistent and above-average performance. A slight deviation from the benchmark begins to appear in the 50kHz to 100kHz test frequency range; however, the component's capacitance stays within acceptable margins.

In high frequency scenarios such as 550kHz and beyond, the component's capacitance far exceeds the statistical benchmark, indicating a superior performance for specific use cases. For example, at 550kHz, the series capacitance reaches 60.57μF, compared to the benchmark's minimum of 2.598μF and maximum of 1.421mF. In a similar fashion, at 600kHz, the TCJD476M025R0100E boasts a series capacitance of 97.78μF, while the benchmark values vary between 2.419μF and 394.4μF.

Analyzed against the statistical benchmark at 10 Volts, the component's performance proves to be consistent and competitive over various test frequencies. The KYOCERA AVX TCJD476M025R0100E Capacitor not only maintains, but also surpasses the benchmark's series capacitance values in certain cases. This in-depth analysis cements the capacitor as a robust and reliable choice for a broad range of engineering applications requiring high-quality Tantalum - Polymer: Molded capacitors.

Series Resistance

In this section, we provide a detailed analysis of the series resistance performance of the KYOCERA AVX part number TCJD476M025R0100E and compare it to the average values of an established statistical benchmark. Series resistance, also known as Equivalent Series Resistance (ESR), is a crucial parameter that influences the capacitor's ability to store and dissipate energy, affecting its behavior in electrical circuits.

At a test voltage of 1 Volt, the capacitor's ESR varies within a range from 20.1Ω at 5 Hz to a significantly low 33.39mΩ at 1 MHz. Observations across the entire test frequency range reveal that this component consistently exhibits a series resistance lower than the average values of the referenced statistical benchmark. For example, at a test frequency of 10 Hz, the ESR is 7.718Ω, placing it notably below the benchmark's average of 18.59Ω. The highest observed value of 20.1Ω, encountered at 5 Hz, remains significantly lower than the benchmark maximum of 282.8Ω. Thus, it demonstrates enhanced efficiency in energy storage and dissipation.

Increased test voltage, such as 10 Volts, reveals a consistent series resistance performance for this capacitor, with 37.26Ω at 5 Hz and a minimum of 27.58mΩ at 550 kHz. Impressively, the capacitor's ESR values maintain optimum levels even at higher frequencies and voltages, remaining within the benchmark limits. This finding underscores the component's consistently low series resistance, which outperforms other capacitors with similar specifications in the market. Therefore, the KYOCERA AVX TCJD476M025R0100E proves to be an ideal choice in applications where low ESR is a critical design factor.

Dissipation Factor and Quality Factor

In this section, we will analyze the performance of the TCJD476M025R0100E capacitor concerning the Dissipation Factor (Df) and Quality Factor (Q), comparing it with statistical benchmark data derived from an array of similar components.

The TCJD476M025R0100E capacitor demonstrates an inverse relationship between the Dissipation Factor (Df) and frequency within the range of 5 Hz to 1 kHz. For instance, at 5 Hz with an applied voltage of 1 Volt, the device exhibits a Df of 0.029, which is low and quite reasonable when compared with the benchmark. As the frequency increases to 50 Hz and 100 Hz, the Df demonstrates an improvement, dropping to 0.014 and 0.012 respectively, further corroborating the solid performance of this component within the specified frequency range.

However, beyond 1 kHz, the Dissipation Factor increases, and the capacitor's performance shows a deviation from the statistical benchmark. At frequencies of 10 kHz, 20 kHz, and 50 kHz, the Df values sit at 0.207, 0.389, and 0.780 respectively, exceeding the benchmark values and signaling suboptimal performance when utilized in high-frequency applications in comparison to other capacitors available in the market.

In terms of the Quality Factor (Q), the component initially displays excellent performance with a Q value of 33.86 at 5 Hz, which further improves to 80.59 at 100 Hz. Maintaining its stability within the low to mid-range frequency spectrum, the Q value sustains a steady 37.61 at 1 kHz. However, as the frequency progresses, the Q factor diminishes considerably, with a drop from 9.31 at 5 kHz to a mere 0.31 at 1 MHz. This decline indicates that the overall performance of the capacitor in these higher frequencies is not congruous with the benchmark standard.

Thus, it is essential to consider these performance aspects concerning the Dissipation and Quality Factors while selecting the TCJD476M025R0100E capacitor for specific applications, as its capability may vary depending on the frequency requirements involved.
